Best Negative Ion Generators to Consider 003

Negative Ion Generator Buyer’s Guide

To choose the best negative ion generator as per your needs, considering the key features of these products is essential. Otherwise, you may end up choosing an inefficient model, which would also lead to a waste of money and effort.

So, let’s briefly look at each of the important factors to consider before purchasing a suitable negative ion generator.

1. Efficiency

For negative ionizers, the efficiency is determined by the number of negative ions emitted per second or in a unit area. The more the number, the better will be the air quality in the room. Additionally, a greater emission would help provide better coverage. This is why it’s absolutely essential to check the details regarding the emission of negative ions by each model.

2. Coverage Area

Coverage is another crucial point to take into account while buying a negative ion generator. After all, the coverage will largely determine its effectiveness for your home.

To ensure that the chosen model provides the perfect coverage, you must estimate the area of the room where you’ll keep the ionizer. Accordingly, you need to verify whether that area falls within the coverage range for a particular model.

The inclusion of fans in ionizers also facilitates greater coverage, as they can easily spread the ions to the entire space. So, make sure you check whether the model includes a fan. Note that smaller models generally don’t use fans since they offer a relatively smaller coverage.

3. Noise Level

Noisy devices can be frustrating; hence it would obviously be best to go for one which works quietly while delivering the desired performance. As such, we’d suggest going through the customer reviews for the model to ensure that it doesn’t produce any disturbing sound.

4. Size

This is a factor often overlooked while purchasing negative ion generators, but it’s important since the space considerations may not be the same for all users. Note that models of various sizes are available, so you should consider the place where it would be kept and how it would be installed.

Naturally, smaller models would be better for homes with limited space and vice versa. But if you want to carry it along for all your travels, it should be portable enough.

Best Negative Ion Generators to Consider 004


That was all about the best negative ion generators out there currently. We hope that, by now, you will be able to zero in on the right model easily. So, go ahead and bring one home to start reaping the benefits of clean and healthy air.

But before we call it a day, we would like to quickly take you through our favorites from the list. If you prefer to go for an ionizer without any filter, the Clarifion GL – 139 would be the best budget buy, in our opinion. On the other hand, for those interested in a model that uses the combined effect of ionization and light therapy, the Nature Bright F40-40 will be an ideal pick.

With that, we’ll sign off for today. Happy shopping!
